Does nothing happen when you press Alt-Tab in Windows 10? Do your applications disappear before you can Tab your way through to them? Or does the app switcher fail to open a program once you’ve selected it?

Many reasons can stop the Alt-Tab keyboard shortcut from working correctly on your computer. Technical glitches, corrupt keyboard drivers, conflicting system settings, etc., are just a few.

Below, you will find several troubleshooting tips and methods to fix issues with Alt-Tab not working in Windows 10. Feel free to skip any that don’t apply.

1. Restart Windows Explorer

In almost all cases where the Alt-Tab shortcut fails to work, you can fix it immediately by restarting the Windows Explorer process.

  1. Right-click the taskbar and selectTask Manager.

  2. SelectMore Detailsto expand the Task Manager.

  3. Scroll down theProcessestab and locateWindows Explorer. Then, right-click it and selectRestart.

  2. PressAlt+Taband see if the key combination works without issues.

2. Reboot the Computer

If restarting Windows Explorer didn’t help, try rebooting your computer instead. That should take care of any minor technical glitches that cause the Alt-Tab keyboard shortcut to not work correctly.

3. Uninstall/Reinstall Keyboard Device

You can rule out any issues with a corrupt keyboard driver by uninstalling and reinstalling your keyboard via Device Manager.

  1. Right-click theStartbutton and selectDevice Manager.

  2. ExpandKeyboards.

  3. Right-clickHID Keyboard Deviceand selectUninstall Driver.

  4. SelectUninstallto remove your keyboard.

  1. Restart your computer. Windows 10 should automatically detect your keyboard and re-install its driver.

4. Install Support Software

Did the issue with Alt-Tab start right after using a new keyboard? Check the keyboard manufacturer’s website (Logitech,Dell,HP, etc.) for any specific device drivers or support software. Install them and see if that fixes the issue.

5. Check Keyboard on Another PC

If you continue to have issues with Alt-Tab not working on your computer, it’s best to connect your keyboard to another PC and test out both keys to rule out any hardware-related problems. If there’s nothing wrong, go ahead with the rest of the fixes.

6. Remove Third-Party Alt-Tab Switcher

Do you have a third-party Alt-Tab program installed on your computer? Despite improving the functionality of the app switcher, it can also break things down. Try removing it from your computer.

  1. Right-click theStartmenu.

  2. SelectApps and Features.

  3. Locate the third-party Alt-Tab program and selectUninstall.

If you can’t remove the Alt-Tab program (if it’s a portable applet, for example), open it and revert any modified settings to their defaults.

7. Enable Peek

Sometimes, Alt-Tab will refuse to switch windows if you’ve disabled Peek in Windows 10. It’s the functionality that allows you to “peek” into the desktop when you drag the cursor to the screen’s lower-right corner. Re-enable it and see if that helps.

  1. PressWindows+R, typesysdm.cpl, and pressEnter.

  2. Switch to theAdvancedtab and selectSettingsunderPerformance.

  8. Turn on the switch next toUse Peek to preview the desktop.

  9. Exit the Settings pane and restart your computer.

8. Update Video Card Drivers

The Alt-Tab app switcher can stop working if you have any outdated video card drivers on your computer. Try updating them.

You can get the latest graphics card drivers by heading over to theIntel,NVIDIA, orAMDwebsites. Alternatively, you can use a driver updater program to update the video drivers on your computer automatically.

9. Update Windows 10

If you continue to have issues, you must update Windows 10. That should take care of any known bugs that prevent the Alt-Tab keyboard shortcut from working correctly.

  1. Open theStartmenu and selectSettings.

  2. SelectUpdate & Security.

  3. Under theWindows Updateside-tab, selectCheck for Updatesand install any pending updates.

Additionally, select theView optional updatesoption and install any hardware driver updates.

10. Run a Malware Scan

A malicious program can hijack your computer and stop core Windows 10 functionalities from working properly. If you haven’t already, use Windows Security to perform a quick scan for malware now.

  1. Open theStartmenu and selectSettings.

  2. SelectUpdate & Security.

  3. Switch to theWindows Securityside-tab.

  4. SelectVirus & threat protection.

Run theSystem File Checker(SFC) via the elevated Command Prompt console to scan and fix any corrupted system files on your computer.

The SFC scan should take several minutes to complete. Reboot your computer afterward and check if Alt-Tab works without issues.

12. Switch to Old Alt-Tab Viewer

Try switching to the older Alt-Tab app switcher (which displays app icons instead of preview thumbnails) and see if that helps.

  1. PressWindows+Rto openRun.

  2. Typeregeditand selectOK.

  3. Copy and paste the following path into the address bar to the top of the Registry Editor window and pressEnter:

Suppose you can’t see theAltTabSettingsregistry key within the Registry Editor. Open an elevated Command Prompt console and run the following command:

REG ADD HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorer /v AltTabSettings /t REG_DWORD /d 1

That should create anAltTabSettingsregistry key with the correct value automatically. You do not have to revisit the Registry Editor, but you must reboot your computer.

13. Tweak Multitasking Settings

Do you use multiple desktops in Windows 10? If so, the Alt-Tab app switcher will not reveal open apps across desktops unless you modify the Multitasking settings.

  1. Open theStartmenu and selectSettings.

  2. SelectSystem.

  3. Switch to theMultitaskingside-tab. Then, open the menu underPressing Alt+Tab shows windowsthat are open on and selectAll Desktops.

The Multitasking screen also includes an additional setting that allows you to tweak the Alt-Tab app switcher’s behavior when you use it with Microsoft Edge. Use the menu under theAlt+Tabsection to determine if you want the app switcher to reveal browser tabs as separate windows or not.

Alt-Tab Your Way Through

Most likely, you ended up fixing Alt-Tab straight off the bat by restarting the Windows Explorer process. If not, the other fixes should’ve helped with Alt-Tab not working. If you still have issues, however, you should tryresetting Windows 10 to factory settings. That should take care of any corrupt settings or other issues stopping your computer from functioning properly.
